Given that MAGICC6 is used in many model intercomparison excercises and as the default model for the creation of the new RCP scenarios, we provide you with a compiled version (for Windows machines) of MAGICC6. If you are an IAM modeller, there are specific solutions for IAM Modellers to obtain MAGICC, if Windows is not for you.


At you will find a short registration form to download your MAGICC6 version. It only takes a minute to complete and we will use the contact information to update you on any new version, if you wish. (Alternatively, download the MAGICC/SCENGEN 5.3 package).

The default RCP settings

You can, if you wish, change all the parameter values for the set of more than 400 input parameters that MAGICC has. However, we recommend you run MAGICC6 using the RCP default settings. These default settings were used to produce the GHG concentrations for the new RCP scenarios and are described here:

  • Meinshausen, M., S. Smith, K. Calvin, J. Daniel, M. Kainuma, J. F. Lamarque, K. Matsumoto, S. Montzka, S. Raper, K. Riahi, A. Thomson, G. Velders and D. P. van Vuuren (2011). "The RCP greenhouse gas concentrations and their extensions from 1765 to 2300." Climatic Change 109(1): 213-241. freely available online

Regarding the CMIP4 and CMIP3 calibrations that were used for creating the RCP default settings, please find more information here:

  • Meinshausen, M., S. C. B. Raper and T. M. L. Wigley (2011). "Emulating coupled atmosphere-ocean and carbon cycle models with a simpler model, MAGICC6: Part I – Model Description and Calibration." Atmospheric Chemistry and Physics 11: 1417-1456. freely available online

Thus, using the RCP default settings, you will get exactly the same version that we designed to perform the runs for the GHG concentrations in the RCP scenario process. This means that if you have a comparable set of input emissions, you could create your own GHG concentration trajectories, as if they would have been part of the RCP scenario process. This should be useful for a wide range of scientific research endeavors. Please note though, that unless we are involved in a joint research or publication project, we usually do not have the time answering user requests. In other words, the version comes as a "take-it-as-it-is" kind of package.
